Chris is incorrect. To check the answer, replace m with 8 and simplify the left side. So m/6 turns into 8/6 which converts to the decimal value 1.333 (use a calculator)
Therefore the original equation m/6 = 48 becomes 1.333 = 48 after you plug in m = 8 and simplify fully. The two sides of 1.333 = 48 are not the same, so m = 8 is not the solution.
--------------------
The solution is actually 288 and we can prove it so like this
m/6 = 48
288/6 = 48 .... replace m with 288
48 = 48 .... use a calculator to compute 288/6
So the solution m = 288 is confirmed
------------------
How did I get this answer? By multiplying both sides by 6
m/6 = 48
6*(m/6) = 6*48 ..... multiply both sides by 6
m = 288
So Chris mistakenly divided both sides by 6, which explains how he got 48/6 = 8 as the solution. Instead he should have multiplied both sides by 6. This is to undo the operation "divide by 6" that is being applied to m in the original equation.
m < 1 = 130°
m < 1 = 130°m < 2 = 50°
We know this is a linear pair, therefore the two angles must add up to 180°
Combine like terms
Isolate the variable
Plug in 26 for x in both of the individual angle equations.
A good way to check if we did this correctly, is to add up the two angles. Because 180 + 50 = 180, we did this correctly.
I hope this helped. Let me know if you have any questions!
Answer:
Step-by-step explanation:
distance = rate * time
rate = distance / time
= 2/3 mile divided by 1/2 hour
= 2/3 * 2/1 = 4/3 mph = 1 and 1/3 mph
His speed is 4/3 mph = 1 and 1/3 mph = 1.3 mph
So
1 mile = (4/3 mph) * TIME
Solving for Time T, it will take him t = 3/4 <--- the RECIPROCAL
and 3/4 hour = 45 minutes
Jack walks 1 mile in 45 minutes = 3/4 hour

Answer:
1/2
Step-by-step explanation:
were gonna need some formula that deals with slope and points. I'm thinking the point slope formula. y2-y1=m(x2-x1) so 10-7=m(-1+7) solve for m so 3=m(6) so m=3/6 or reduce to m=1/2
